Hi All,

I need to understand how to track the star with Dosbsonian telescope Mount?

First I need to write some information:

Let say:

My observing site Latitude (Singapore) = 1' 19" 48" deg and longtitude = 103'48"49" deg

I am observing the star located at Altitude = 45 deg and Azimuth = 150 deg

Observing local Time: 10.45pm

Find out:

1: Altitude deg movement per minute Rate

2: Azimuth deg movement per minute Rate

So Now, What will be the Altitude and Azimuth movement deg per minute rate? Is there any formula for this to calculate so I can write into the software?

Please show me how you calculated.

Best regards

Mitoo
